Method and printer for printing on print media

A method for a printer, the printer comprising a transport device comprising an endless transport belt supported on a pair of support rollers, a medium support plane being defined between the pair of support rollers, and a print station being provided over the medium support plane, wherein the method comprises the steps of:

• transporting in parallel a plurality of individual print media perpendicular to a scanning direction of the print station on the medium support plane, the print media having different dimensions;
• determining positions of the individual print media;
• based on the determined positions of the individual media, jetting marking material for forming a designated image specific for each print medium on each respective print medium,
• wherein the above steps are repeated such that print media are printed in a plurality of parallel lanes on the medium support plane perpendicular to the scanning direction,
• wherein the method comprises the step of enabling or disabling each individual lane of the plurality of parallel lanes in order to respectively facilitate or prohibit jetting of the marking material at the individual lane;
• and
• wherein the method comprises the step of disabling at least one lane from one of the sides of the medium support plane parallel to the transport direction of the print media and, while printing on the print media, reducing a swath of the print station in the scanning direction so that the at least one disabled lane is not scanned by the print station.
